Start a logging system for bootstrappy bits.
Enable with -Dswarm.bootstrap.log.NAME Where NAME is a simple single word, such as: runtime Use via BootstrapLogger.logger( "runtime" ) Currently all levels are enabled. If you want to use it, you'll need a dependency on org.wildfly.swarm.bootstrap, with optional="true" in your module.xml.
